Re: Something amusing about Fritz 18 (or any Fritz)
Hi,
White is lost anyway, his pieces are tied to the defense of the weak pawns (c3, h2 and a2) while Black can create a passed pawn on the kingside that eventually decide. This is a possible critical position:

and here he can simply resign.
Fritz 5.32 says -6.

If Ke2 force repetition of previous position in the game Fritz is looking at it then it can explain a draw evaluation because a lot of engines evaluate first repetition as a draw with the logic to save time on the clock because if the engine is winning in a game it does not need to make a repetition and if the engine is losing the opponent will probably not allow repetition but win faster.
